Description générale

The Titrisol® reference buffer concentrate [citrate/hydrochloric acid; pH=2.00±0.02 (20 °C)] is analyzed in the ISO/IEC 17025 accredited calibration laboratory with a combined glass electrode and 5-point calibration according to DIN 19268 against a certified primary standard reference material following DIN 19266. The Titrisol® concentrated buffer material combines ease of use and maximum precision for the routine calibration and monitoring of pH instruments. To prepare the ready-to-use pH buffer solution, simply dilute the Titrisol® buffer concentrate.

Application


  • Sample preparation for mass spectrometry: Poly(ethylene glycol) was employed in a solvent-free sample preparation method for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, enhancing the analysis of polymer blends and contributing to advanced analytical techniques (Dalgic and Weidner, 2024).


Caractéristiques et avantages

  • Traceable to primary standard reference materials from NIST and PTB
  • Analytical standard Grade
  • Uncertainty data and traceability are documented in a comprehensive and batch-specific Certificate of Analysis.

Remarque sur l'analyse

pH-value (20 °C): 2.00 +/- 0.02
Measured after dilution to 500 ml with a combination glass electrode after multiple point calibration (according to DIN 19268) with reference materials for the preparation of standard buffer solutions according to DIN 19266.
